COUPLI G-POCKET.

To all whom it may concern:

Be it known that I, FREDERICK H. BIRD,

a citizen of the United States, and resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and I usefulImprovements in Coupling-Pockets, of which the following is aspecification.

My invention relates to railwaycars and has partlcular reference toanovel coupler pocket for use as an attaching means for car couplers tothe end sills of locomotive tenders and similar cars. I

The invention is intended as an improvement on the patent to DickersonNo. 1,087,222, under which my .assignee is a licensee. 1

An object in the presentconstruction is to provide against-thepossibility of the shelf, which is separable fromthe pocket member,becoming loose because of the difliculty in maintaining the fasteningbolts in a tight condition.

A further object is to providemeans for upholding the shelf wherein the,holding bolt or pin is in shear instead of in tension.

A still further object is to provide a holding pin or bolt which shallbe in double shear.

The invention will be more readily understood by reference to theaccompanying drawings, wherein-- Figure 1 is a side elevation of acoupler.

pocket constructed in accordance with vmy invention, and 7 Fig. 2 is asectional view on the line 2-2 of Fig. 1.

Referring more particularly to the draw ings, it will be seen that thepocket includes a vertical web 10, by means of which the 1 pocket issecured to an end sill or other portion of a car. Projecting from oneside of the web is a pocket having laterally diverging. side walls 11and parallel top and'bottom walls 12,13 respectively' At 'tl16 top andbottom of thepocket and secured to the upper and lower walls-12,13, areapertured ears or lugs 14, 15, a pair of such lugs being provided onboth upper and lower.

walls, each one of the lugs constituting the pair being spaced apart andlying one on each side of the pivot pin-hole 16 through the pocket.Projecting outwardly from the web 10, oneachside of the pocket, are lugsmade reversible.

Specification ofLetters Patent. Patented Apr, 24, 1917, Applicationfiled June 28,1915." Serial No. 36,700.

17, 18, a pair of these lugs being disposed on each side of the pocketand both above and below the center line thereof, the lugs of a pairbeing spaced apart vertically to form an opening or jaw therebetween.

The parts heretofore described are all cast integral. The shelf, bymeans of which the coupler is supported in horizontal position, consistsin a flat shelf portion 19 and a bifurcated opposite portion consistingin arms 20, the endsof which lie between the lugs 18, as shown inFig. 1. Intermediate the arms and the shelf portion I provide bearings21, spaced apart a distance slightly the bearings and the ears 15, thepin being held in place by a cotter 23. The upper and lower portions ofthe pocket member are duplicated in order that the pocket may be Theshelf'portion may be strengthened by suitable longitudinal'ribs 24 andhorizontal ribs 25. As shown, the load is carried by a large pin whichis'in double shear, and there is no possibility of the parts becomingloose because of ineflicient holding capacity of nuts. Furthermore, thepin may be of relatively large size, and therefore the wear thereon willbe reduced to a mlnimum.

I claim:

1. In a device of the class described, the combination of a pocketmember having apertured lugs, stop lugs also secured to said'pocketmember, a shelf having a flat bearing portion, an arm engaging said stoplugs, and a pin passing horizontally through said apertured lugs andthrough said shelf member intermediate its ends, substantially asdescribed.

2. In a device of the class described, the combination of acouplerpocket,having a? rear wall and a floor, an apertured lug projectingdownwardly from said floor, a shelf horizontally pivoted to saidapertured lug, and a pair of lugs projecting forwardly from said rearwall and providing a space therebetween within which space the rear endof said'shelf is adapted to be accommodated,

substantially as described.

3. In a coupler pocket the combination of a pocket member including arear Wall and tween the lugs projecting from said rear a floor, anapertured lug projecting from Wall, substantially as described. 10 saidfloor, a pair of apertured lugs project- Signed at Chicago, Illinois,this 23 day ing from said rear wall, a shelf having of June, 1915.
